Description

Technical Field

[0001] The present invention relates to the technical field of polymer material recycling, and more particularly, to a recycling system for preventing blockage of TPE particles. Background Art

[0002] TPE (thermoplastic elastomer) particles are a special plastic material with high strength, high resilience and injectable processing, and have a wide range of applications. During the production, processing and use of TPE particles, it is inevitable to generate some waste materials and scraps. Recycling and reusing these particles has important economic and environmental significance.

[0003] During the use of TPE particles, they will be contaminated with various impurities and foreign matters, such as oil stains, dust, metal chips, etc. If these impurities are not removed by cleaning, the quality and performance of recycled TPE particles will be affected. Therefore, it is often necessary to use relevant cleaning equipment to clean TPE particles to ensure the purity of the recycled TPE particles and improve the quality of the recycled products. During the cleaning and recycling process of TPE particles, since TPE particles will carry various impurities and foreign matters during the cleaning process, these substances and the TPE particles themselves are prone to deposit and gradually accumulate at the bottom of the box under the influence of gravity and the flow of the cleaning liquid, forming one or more layers of tight accumulations. This deposition and blockage phenomenon not only reduces the effective flow area of the cleaning liquid, lowers the cleaning efficiency, but also causes the cleaning liquid to be unable to fully contact and clean the particles at the bottom, thus affecting the overall cleaning quality.

[0004] Therefore, it is necessary to design a recycling system for preventing blockage of TPE particles to solve the problems of low purity of recycled TPE particles and blockage of the device existing in the traditional recycling device. Summary of the Invention

[0024] The temperature sensor is arranged at the top of the eddy current generation chamber, the current temperature value of the eddy current generation chamber collected by the temperature sensor is ΔW, the central processing module is configured with a temperature threshold W, and the central processing module compares the temperature threshold W with the current temperature value ΔW of the eddy current generation chamber to determine whether the current temperature inside the eddy current generation chamber meets the preset standard;

[0025] When ΔW < W, the central processing module controls the heating component to heat the eddy current generation chamber until ΔW = W;

[0026] When ΔW > W, the central processing module controls the cooling component to cool the eddy current generation chamber until ΔW = W;

[0027] Among them, the eddy current generation chamber satisfies the process of separating the impurities in the TPE particles.

[0028] Further, the conveyor belt is divided into a circulating belt and a collecting belt after the infrared spectrometer. The infrared spectrometer collects the infrared spectrum of the current TPE particles to form a spectrogram and transmits it to the central processing module. The central processing module compares the spectrogram of the current TPE particles with the standard spectrogram of pure TPE to determine whether there are impurities in the current TPE particles.

[0029] If the spectrogram of the current TPE particles is consistent with the standard spectrogram of pure TPE, Figure 1 then the central processing module determines that there are no impurities in the current TPE particles, and uses the magnetic control unit to draw the current TPE particles to the collecting belt. The collecting belt sends the TPE particles to the sealed recycling device.

[0030] If the spectrogram of the current TPE particles is inconsistent with the standard spectrogram of pure TPE, the central processing module makes a further determination of the current TPE particles.

[0039] 2. In the eddy current treatment device, the spiral flow guiding grooves in the eddy current generation cavity cooperate with the rotary drive unit at the bottom, enabling the fluid in the cavity to generate stable and efficient eddy currents. These eddy currents can further disperse the TPE particles, ensuring sufficient contact between the particles and between the particles and the fluid, which helps to remove the residual impurities on the particle surface and also provides a more uniform material state for subsequent treatment steps.

[0040] 3. In the magnetically controlled conveying device, multiple magnetically controlled units composed of electromagnets are arranged in an array on both sides of the conveyor belt.

The metering unit can accurately record the weight and volume information of the TPE particles, facilitating the statistics and management of the recycling quantity and providing data support for cost accounting and resource utilization in the production process.

The drawings are only for the purpose of showing the preferred embodiments and are not considered as limiting the present invention. Moreover, throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0043] Figure 1 is a functional block diagram of the recycling system for preventing blockage of TPE particles provided by the embodiment of the present invention. Detailed Embodiments

[0044] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0045] Refer to Figure 1, in some embodiments of the present application, a recycling system for preventing blockage of TPE particles includes: an adsorption separation device provided with a multi-layer adsorption structure for preliminarily adsorbing and separating impurities in the TPE particles;

[0046] A vortex treatment device connected to the adsorption separation device. The vortex treatment device includes a vortex generation chamber with a spiral guide groove inside and a rotation drive unit for driving the fluid in the chamber to rotate. The rotation drive unit is arranged at the bottom of the vortex treatment device;

[0047] A magnetically controlled conveying device connected to the vortex treatment device. The magnetically controlled conveying device includes a plurality of magnetically controlled units for regulating the magnitude and direction of the current, a conveyor belt for directionally conveying the TPE particles, and an infrared spectrometer for detecting the characteristics of the TPE particles. Each magnetically controlled unit is composed of an electromagnet, and the electromagnets are distributed in an array on both sides of the conveyor belt. The infrared spectrometer is arranged on both sides of the middle end of the conveyor belt;

[0048] A sealed recycling device connected to the magnetically controlled conveying device. The sealed recycling device includes a sealed recycling tank for forming a closed space, a vacuum pumping unit for creating a vacuum environment in the closed space, a nitrogen filling unit for filling nitrogen into the vacuum environment, and a metering unit for recording the weight and volume information of the TPE particles;

[0049] A central processing module is respectively connected to the adsorption separation device, the vortex treatment device, the magnetically controlled conveying device, and the sealed recycling device by signals. The central processing module is used to receive the data transmitted by each module, determine the recycling situation of the TPE particles within a cycle according to the data. If it is determined that the recycling of the TPE particles is not completed within the cycle, the central processing module adjusts the parameters of the vortex treatment device and the magnetically controlled conveying device to corresponding values.

[0050] Specifically, the TPE particles to be processed enter the adsorption separation device. Using its multi-layer adsorption structure, the impurities in the TPE particles are preliminarily adsorbed and separated. The impurities are adsorbed on the multi-layer adsorption structure, while the relatively pure TPE particles continue to be conveyed to the eddy current treatment device. The TPE particles after adsorption separation enter the eddy current generation chamber of the eddy current treatment device. At the same time, the fluid is also introduced into the eddy current generation chamber. The rotation drive unit arranged at the bottom of the eddy current treatment device starts to work, driving the fluid in the chamber to rotate. Since a spiral flow guide groove is arranged inside the eddy current generation chamber, under the action of the rotation drive unit, the fluid generates eddy current motion. The TPE particles are fully dispersed and stirred in the eddy current, further removing the impurities that may remain on the particle surface. The mixture of the TPE particles and the fluid after eddy current treatment enters the magnetron conveying device. The conveyor belt of the magnetron conveying device starts to operate, driving the TPE particles to move forward. A plurality of magnetron units (composed of electromagnets and arranged in an array distribution form) distributed on both sides of the conveyor belt regulate the magnitude and direction of the current according to the instructions of the central processing module. By changing the current, the electromagnets generate magnetic fields with different intensities and directions, thereby performing directional conveying and position control on the TPE particles to ensure that the TPE particles move along a predetermined trajectory on the conveyor belt. The TPE particles after magnetron conveying and feature detection continue to move forward and enter the sealed recovery device. The sealed recovery tank first forms a sealed space, and the vacuum pumping unit is started to pump out the air in the sealed space to form a vacuum environment. Then, the nitrogen filling unit fills nitrogen into the vacuum environment to prevent the TPE particles from being oxidized or contaminated during the recovery process. During the process of the TPE particles entering the sealed recovery tank, the metering unit real-time records the weight and volume information of the TPE particles and transmits this data to the central processing module.

[0051] In some embodiments of the present application, when the multi-layer adsorption structure adsorbs and separates the impurities in the TPE particles, it includes:

[0052] The outermost layer of the multi-layer adsorption structure is set as a pre-adsorption layer. The surface of the pre-adsorption layer is provided with filter holes. The pre-adsorption layer is used to intercept impurities with sizes larger than the filter holes. The middle layer of the multi-layer adsorption structure is set as a specific adsorption layer. Specific adsorption materials are arranged inside the specific adsorption layer. The innermost layer of the multi-layer adsorption structure is provided with a fine adsorption layer, and the fine adsorption layer is used to adsorb dust.

[0053] Specifically, when specific adsorption materials are arranged inside the specific adsorption layer, it includes:

[0054] The adsorption separation device is provided with an impurity identification unit, and the central processing module selects specific adsorption materials according to the impurities identified by the impurity identification unit;

[0055] If the impurity recognition unit recognizes that the impurity in the TPE particles is metal debris, the specific adsorption layer uses a magnetic adsorption material;

[0056] If the impurity recognition unit recognizes that the impurity in the TPE particles is oil stain, the specific adsorption layer uses a hydrophobic and lipophilic adsorption material;

[0057] If the impurity recognition unit recognizes that the impurities in the TPE particles include both metal debris and oil stain, the specific adsorption layer uses a double-layer specific material to adsorb the impurities;

[0058] When the specific adsorption layer uses a double-layer specific material, the magnetic adsorption material is on the surface of the specific adsorption layer close to the pre-adsorption layer, and the hydrophobic and lipophilic adsorption material is on the surface of the specific adsorption layer close to the fine adsorption layer.

[0059] Specifically, the adsorption separation device is provided with a backwashing unit, the backwashing unit is arranged above the adsorption separation device, and the central processing module controls the backwashing unit to perform backwashing on the adsorption separation device for i cycles, where i is a natural number greater than or equal to 2, and the interval between each cycle is 10 minutes.

[0060] It can be understood that the design of the multi-layer adsorption structure realizes the step-by-step and fine adsorption separation of different types and sizes of impurities in the TPE particles. The outermost pre-adsorption layer effectively intercepts larger impurities through the filter holes, preventing these larger particles from clogging or affecting the subsequent adsorption layer, and playing a role of preliminary filtration. By setting the impurity recognition unit and the central processing module, the specific adsorption material can be flexibly selected according to the actually detected impurity type. When the impurity is metal debris, the magnetic adsorption material can efficiently adsorb the metal debris; when the impurity is oil stain, the hydrophobic and lipophilic adsorption material can effectively remove the oil stain; when both metal debris and oil stain exist, the double-layer specific material is used, and the positions of the magnetic adsorption material and the hydrophobic and lipophilic adsorption material are reasonably arranged to realize the simultaneous adsorption of multiple impurities, improving the adaptability and processing ability of the adsorption separation device to different impurity conditions, and enhancing the practicability and versatility of the device. The backwashing unit set in the adsorption separation device is controlled by the central processing module to perform backwashing on the adsorption separation device at a certain period (the interval between each cycle is 10 minutes, and the number of cycles i is greater than or equal to 2). This design can timely remove the impurities adsorbed on the surface and inside of the adsorption layer, prevent the excessive accumulation of impurities on the adsorption layer from affecting the adsorption effect and the service life of the adsorption layer. By regular backwashing, the activity and adsorption capacity of the adsorption layer are maintained, the replacement frequency of the adsorption layer is reduced, the operation cost and maintenance workload are reduced, and the operation efficiency and economy of the adsorption separation device are improved.

[0061] Specifically, impurity collection ports are evenly distributed on the inner wall of the eddy current generation chamber. The impurity collection ports are connected to impurity collection pipes, and a filter screen is arranged in the impurity collection pipes.

[0062] It can be understood that after impurities enter the impurity collection pipe through the impurity collection ports, the filter screen in the pipe can intercept and separate the impurities, separating the impurities from the fluid. This can facilitate the subsequent treatment of the collected impurities, and at the same time avoid the influence of impurities on the subsequent treatment process, improving the efficiency and stability of the entire treatment system.

[0063] In some embodiments of the present application, a temperature control unit is arranged inside the eddy current generation chamber. The temperature control unit is used to keep the temperature inside the eddy current generation chamber stable. The temperature control unit includes a temperature sensor, a cooling component, and a heating component. The temperature sensor transmits the temperature data collected in real time inside the eddy current generation chamber to the central processing module.

[0064] Specifically, when the temperature control unit is used to keep the temperature inside the eddy current generation chamber stable, it includes:

[0065] The temperature sensor is arranged at the top of the eddy current generation chamber. The current temperature value inside the eddy current generation chamber collected by the temperature sensor is ΔW. The central processing module is configured with a temperature threshold W. The central processing module compares the temperature threshold W with the current temperature value ΔW inside the eddy current generation chamber to determine whether the current temperature inside the eddy current generation chamber meets the preset standard;

[0066] When ΔW < W, the central processing module controls the heating component to heat the eddy current generation chamber until ΔW = W;

[0067] When ΔW > W, the central processing module controls the cooling component to cool the eddy current generation chamber until ΔW = W;

[0068] Among them, the temperature sensor collects the temperature data inside the eddy current generation chamber in real time and transmits it to the central processing module. The central processing module makes comparisons and judgments based on the preset temperature threshold, and then precisely controls the operation of the heating component or the cooling component. This automated temperature control method can quickly respond to temperature changes, achieve precise temperature adjustment, keep the temperature inside the eddy current generation chamber always within the ideal range, and improve the accuracy and efficiency of temperature control.

[0069] In some embodiments of the present application, the conveyor belt is divided into a circulation belt and a collection belt after the infrared spectrometer. The infrared spectrometer collects the infrared spectrum of the current TPE particles to form a spectrum diagram and transmits it to the central processing module. The central processing module compares the current TPE particle spectrum diagram with the standard spectrum diagram of pure TPE to determine whether there are impurities in the current TPE particles;

[0070] If the current TPE particle spectrogram is consistent with the standard spectrogram of pure TPE Figure 1 then the central processing module determines that there are no impurities in the current TPE particles, and the current TPE particles are pulled to the collection belt through the magnetron unit, and the collection belt sends the TPE particles to the sealed recovery device;

[0071] If the current TPE particle spectrogram is inconsistent with the standard spectrogram of pure TPE, the central processing module makes a further determination of the current TPE particles.

[0072] In some embodiments of the present application, when the central processing module makes a further determination of the current TPE particles, it includes:

[0073] The central processing module is configured with an impurity content threshold Z. The central processing module calculates the content ΔZ in the current TPE particles according to the proportional relationship between the intensity of the impurity-related peaks in the spectrogram and the intensity of the TPE spectrogram peaks. The central processing module compares the impurity content threshold Z with the content ΔZ in the current TPE particles to determine whether there is a blockage in the eddy current treatment device;

[0074] When Z ≤ ΔZ, the central processing module determines that there is a blockage in the eddy current treatment device;

[0075] When Z > ΔZ, the central processing module determines that there is no blockage in the eddy current treatment device, and the current TPE particles are pulled to the circulation belt through the magnetron unit, and the circulation belt sends the TPE particles to the initial position of the system;

[0076] Wherein, the current TPE particle spectrogram satisfies being inconsistent with the standard spectrogram of pure TPE.

[0077] Specifically, the eddy current treatment device is provided with a vibration unit, and the vibration unit is used to start vibrating when the central processing module determines that the eddy current treatment device is blocked.

[0078] It can be understood that the central processing module configures the impurity content threshold Z, and calculates the impurity content ΔZ in the current TPE particles according to the proportional relationship between the intensity of the impurity-related peaks in the spectrogram and the intensity of the TPE spectrogram peaks, so as to judge whether the eddy current treatment device is blocked. When it is determined that there is no blockage in the eddy current treatment device, the central processing module pulls the current TPE particles to the circulation belt through the magnetron unit, and the circulation belt sends the TPE particles back to the initial position of the system, realizing the cyclic processing of TPE particles. The vibration unit provided in the eddy current treatment device starts vibrating when the central processing module determines that the device is blocked. Vibration can effectively loosen the impurities and particles blocked inside the eddy current treatment device and help them drain smoothly, thus solving the blockage problem.

The multi-layer adsorption structure provided in the adsorption separation device can effectively adsorb and separate impurities in the TPE particles, improve the purity of the TPE particles, thereby ensuring the quality of the recycled TPE particles, and enabling the recycled TPE particles to better meet the requirements of reprocessing and use. In the eddy current treatment device, the spiral guide groove in the eddy current generation cavity cooperates with the rotary drive unit at the bottom, which can make the fluid in the cavity generate stable and efficient eddy currents. These eddy currents can further disperse the TPE particles, enabling full contact between the particles and between the particles and the fluid, helping to remove the impurities remaining on the particle surface, and at the same time providing a more uniform material state for subsequent treatment steps. In the magnetically controlled conveying device, multiple magnetically controlled units composed of electromagnets are arranged in an array on both sides of the conveyor belt, which can accurately control the magnitude and direction of the current, thereby realizing the directional conveying and position control of the TPE particles on the conveyor belt. The infrared spectrometers arranged on both sides of the middle end of the conveyor belt can perform characteristic detection on the TPE particles in real time, and can quickly and accurately identify information such as the composition and purity of the TPE particles, providing an important basis for subsequent treatment and quality control.
